What happens to the magnetic field produced by a given current in the conductor when the distance increases?
- AIt decreases
- BIt stops
- CIt increases
- DIt stays the same
Solution & Step-by-step Explanation
The magnitude of the magnetic field (B) produced by a straight current-carrying conductor at a given point is inversely proportional to the distance (r) from the conductor.
Mathematically, it is given by:
B∝
r
1
Therefore, as the distance from the conductor increases, the strength of the magnetic field decreases.
Mathematically, it is given by:
B∝
r
1
Therefore, as the distance from the conductor increases, the strength of the magnetic field decreases.
